  • root
  • swap
  • home

I tried to make the RAID5 array bootable using boot-repair from the UbuntuSecure disk. I get GRUB2 startup screen with the list of kernels, but the system doesn't start. It end up with some error message that tell me that it can't find LVM volumes:

Loading, please wait...

Unable to find LVM volume lvm0/swap
Gave up waiting for root device [...]
